Only some sample areas are located in focus due to limited confocal depth of field. A high-speed reflected unit allows you to quickly find a sample focus areas and use them for Raman measurements. This provides a significant gain in time and allows you to immediately use a high numerical aperture objective to record high spatial resolution Raman maps
